Ok heres what I want to do.

I just kinda want to make some reasonably small (5'x4') mini walls to just kinda place around a drum kit. I dont really want to stop sound, although that would be kinda nice, I really just wanna reduce echo and have more control over the sound.

We were plannin on constructing a 2x4 frame that is 5'x4' with 2 inches of air space in between 2 particle boards or plywood.

Here are some questions:
1) What is the best amount of air space inbetween the boards? At what point does it become overkill?

2) Should I make an additional chamber and fill it with some sort of insulation?

3) What type of wood sould be used for the outer layers? Will particle board work or should I go with plywood or drywall?

The primary use of this wall will be to just kinda kill some echo. Maybe this is just a retarded idea? I dunno. I just kinda wanna build something. Please help me out. Any comments, ideas, whatever. Thanks.
 
I'd only bother to use one sheet of particle board KingNothing. Unless you make the whole thing airtight it will have limited sound isolation so even two sheets would be overkill. I'd put insulation on one side so you can turn them around and change the surface from bright to dead.

my 0.2c :)

Thanks John.

A couple of questions if you dont mind. Youll have to excuse my ignorance, studio building is definately not my strong suit.

1) I fully understand this setup will not yield any sort of instrument isolation, but how well will it deaden the sound and kill echo?

2) You recommend just going with basically a sheet of something with different types of foam on each side. What types of foam will achieve this bright sound and what for the dead sound?

You ever have any experience with that Auralex Sheetblok stuff? Would that help me out at all? Its not in the budget now but its something maybe I could look into.

Thanks for the help so far, I really appreciate it.
 
Oh, one other thing. How would I make it airtight if I wanted to go that route? How well would this work if it were to be airtight?

Thanks again.
 
well if you faced the foam side to the drums it would deaden the highs down to around 500Hz, whereas if you put the straight panel side it would reflect the sound and provided they weren't parallel would still break up the standing waves yet liven the kit. Or you could use a combination of both surfaces.

I suppose you could make it airtight if you used rubber seals between the panels and you could get a reasonable sound transmission coefficient (STC) say around 35 - 45db.

Thank you again. Youre really a big help. I do appreciate it.

How well would something like caulk work to make it airtight?
 
chaulk is the best thing to use for that, make sure you buy the 20 years or more rated one, cheap from a place like Home Depot. The 20 year rated one stays flexible, other kinds tend to harden and become useless.

Another thing you could do to save costs, as foam is quite expensive, is to make one side solid, place a layer of rockwool on the inside, then cover it with 5" wide strips of ply, spaced 2" apart. A 1" gap, and onother layer of strips offset from the first one. Cheap and effective
 
Awesome. Thats cool. Ill have to figure out which path to take now. Thanks for that idea.
